The Siemens touch screen flush-mounted PM2.5 & IAQ controller with KNX or RS485 Modbus compatibility. It operates on AC 230 V and features a large backlit display for easy viewing. This controller supports PM2.5 control, CO2 control, or both, making it ideal for ventilation applications. It also displays room temperature, outside temperature, VOC, and relative humidity. The PM2.5 & IAQ controller offers multiple operating modes and has inputs for external sensors. It can be integrated into KNX systems and third-party systems via group addressing. With its Modbus RTU slave mode, it can be easily commissioned and controlled via third-party tools.
